SPECIFICATION forming part of Letters Patent No. 752,064, dated February16, 1904. Application filed Qctober 11, 1902. Serial 110.126,!)31. (K0specimens.)

To all whom it may concern: Be it known that we, JAMES O. GREEN andHARRY T. MARTIN, citizens of the United States, residing at Whitewater,in the. county of Walworth and State of Wisconsin, have invented a newand useful Art and Process of Consolidating Peat, of which the followingis I use of great power.

a specification. I

This invention relates to the process of consolidating peat by forcingit through'a tube or die; and the'object thereof is to produce a moredense and compact article of peat fuel, Heretofore peat containing thenatural. fiber has been compressed by pushing it through a tube or diewith a plunger. While the density of the peat may be increased to aconsiderable extent by a pushing or pressing plungerQit cannot beconsolidated into a hard substance, like coal, by this means, because ittakes too much power and the spring of the fiber prevents consolidationand pressure does not release the tar. When, however, a hammer issubstituted for the press'and the fiber is destroyed by grinding, theheat produced by hammering the peat-powder when dry releases the tar andthe particles of peat can be pounded together into a solid mass withoutthe Tn our invention therefore we use any suitable device or contrivancefor hammering or pounding the peat through a tube or die in carrying outour process, as follows: First, dry peat is ground into a fine powder;second, the peat-powder is pounded in a tube or die by any suitablehammeringmachine delivering a succession-of sharp quick blows withsufficient rapidity to produce heat mering or pounding with sufficientrapidity to produce heat enough by the impact to release the tar in thepeat for the purpose of binding the whole together.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
